Telford Council Zero Carbon Strategy
We were commissioned by Telford and Wrekin Council to produce a thermal upgrades feasibility study for 9 council owned buildings to establish whether thermal insulation and building services could be retrofitted to secure funding opportunities.

Challenge
The buildings under investigation were ranging from offices to leisure centres and theatre. They were built, on average, in the 1980s with little to no upgrades made.
Producing a financial/viability model based on the proposed energy saving systems required the creation of Digital Twins and extensive analysis of energy usage data. We tested different retrofit solutions in the Digital Twin of each building and calculated energy and carbon savings.
Solution
To establish levels of thermal insulation and building services efficiency, we conducted non-intrusive energy audits. We also analysed gas and electricity metering data to investigate energy usage patterns across different years.
We adopted the innovative solution of Digital Twins; this involves the generation of dynamic thermal models based on the buildings in operation. A digital replica of each building was modelled and calibrated to achieve similar performance with the real case building. In some cases, calibration precision reached 1% discrepancy between the actual building and digital twin.
For each building, our financial/viability model indicated:
- Products and specifications
- All capital cost and all operational cost
- Estimates of anticipated benefits including energy efficiency savings and carbon savings
- Any associated risks and mitigations
Energy saving potential
In total, it has been concluded that more than 1,061 MWh of energy and 224 tonnes of CO2 emissions can be saved if the fabric and energy efficiency measures are implemented. The energy savings reduction range from 4% to 37%, with an average reduction of 27.5%.
